Isn’t it a bit different though? Gearbest are in China and don’t have resellers or operate out of Europe in any way. We order things from them online and they send them in the post. I get that they have an EU warehouse but that’s beside the point i think, they could easily just lose it and ship everything from China or other territories.
Whereas Microsoft products are directly sold in every computer store all over the world. I think it would be much harder for the EU to have any impact on gearbest.
It would be interesting to see how this would play out, should something like this ever happen.
